To'aZZ whom it bury concern:

Be it known that I, ADRIAN F.'WOLFF, a

State of Connecticut, have invented a certain new and useful Improvement in Powder- Can Tops, of which the following is a full, clear, and exact description. I I

This invention-relates to the class of cans or similar receptacles for containing powdery substances, which are -to be dispensed through a hole or holes in the top, .and includingmeans for opening and closing the hole or holes as desired. Such'tops have been used on cans andother receptacles for toilet powder and other like powders, but there is always more or less waste or undesirable escape of the owder between the constituent shells of]; e top, due to the loose fitting of these shells; and it is the object of the present invention to fit the shells together so tightly as to obviate this undesirable escape of; the powdery contents I of the receptacle, without impairing tlfienfreedom of movement of the movable The invention consists of a powder can p,

erly perforated for the escape of the pow er, and a movable shellalso perforated so that its hole or holes may be brought into register with the hole or holes inthe fixed shell to permit the desired escape-0f the powder, the two shells being united by a rivet which serves as an axis upon which-the movable'shell turns, and this rivet being headed up on a spring washer on the fixed shell, in' such way that the spring washer constantly maintains tension uponthe rivet sufficient to draw the movable shell into such intimate contact with the fixed shell as to prevent the escape and consequent waste of the powder when the top is purposely closed, and also in such way as not to interfere with the freedom of movement of the I movable shell, all as I will proceed now more --particularly to Set forth and finallyclaim.

I In the accompanying drawings illustrating the lnvention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view, illustrating my invention as app led to a powder can top having a sinimpalpable of the. class described, comprising a fixed shell pro tion. Fig. 3 is'a vertical'cross-section.

l is the breast of the can or receptacle, of

' any suitable shape, and Zis the fixed shell of fixed shell and millet knurled'or otherwise .gle' opening, the parts shown withthe opening uncovered. Fig. 2 is a side eleva-' roughened to; afi'orda finger-grasp for turning the said 'shell. A hole or holes 9 is or are madein the movable shell to,register with the hole or holes 4 in theiixed shell. is also provided with asegmental .slot 10 which cooperates with the stop-lug 5 to limit the extent: of rotation of 'the movable shell with-relation to the'fixed shell. A central.

perforationis made in the movableshell to register with the hole in the washer 6 in the fixedshell, and the two shells, being arranged as in the drawings, are then unitedby a rivet 11. whose shank is passed through the central perforations and upset I or clenched at 12- against the inner'face of the washerfi. Inasmuch as the metalyof "such'tops is thin, the

The shell 7 washer 6 serves as a'spring, drawing upon the rivet 1:1 tohold the movable shell in such in timate contact with the inner or fixedshell as to obviate the leakage and waste of thepo-wdery contents of-the receptacle, and yet not to interfere at'all with the freedom of movement of the outer shell in. bringing its hole or v holes into and out of register with the hole or holes of the fixed shell.

The washer?) is most economically made as an integral part of the fixed shell, by depre s'sing the central portion thereof, as shown," although the invention. might be carried. out by using a separate spring-washer.

i As already inchcated,.the washer-like projection' acts as a sort of spring, and thereby enables the rivet to hold the outer shell tight down upon and against the inner shell, so as to make a practically perfect seal to prevent the escape of the powder, and at the same time it insures a smooth Working fit between the parts.

What I claim is 1. Apowder can top, comprising a perforated fixed shell having a central Washer-like portion servingas a spring, an outer movable shell applied externally to and supported directly upon the fixed shell, and a rivet passed through the two shells and the washer-like portion and headed up against the inner side of said portion so as to hold the outer shell in intimate contact with the inner shell and serving'asan axis for the outer shell to pere Init its rotation on the inner shell to cover and uncover the perforation therein. a

2. A powder cantop, comprisin a perfointegral washer-like erforated depression, an outer movable shell applied to the fixed shell, and a rivet p assed through the twoshells and the depressionand clenched or headed up against the inner side of the Washer-like depression so as to hold the outer shell in intimate contact with the inner shell.

In'testimony whereof I have hereunto set my hand this 1 5th day of February A. D. 1906. ADRIAN F.. WOLFF.
